VOGUE cover girl Victoria Beckham is adding yet another string to her singer/designer bow - by becoming a cartoon character.

Beckham has been animated for a special episode of SpongeBob SquarePants called The Clash of Triton. The 30-minute episode will be shown in the US on July 5 on Nickelodeon.

"I was so thrilled as my children love the show," Beckham, who plays the role of Queen Amphitrite, tells this morning's Metro. "When I told the boys I was going to be on the show, they were so excited. I had such a great time recording the voice of Queen Amphitrite. How fun to be queen for a day!"
